We prove two basic properties of a homomorphism f from a group G to a group H. First, we prove the homomorphism maps the identity of G to the identity of H, that is: f(e) = e. Then we prove the homomorphism maps inverses of a to corresponding inverses in H. So, f(a^-1) = [f(a)]^-1. #abstractalgebra #grouptheory
